Hey,

After formatting and reinstalling my MBA, I noticed that YouTube5 extension for Safari didn't work properly. Most 720p and 1080p video lags so much that I can't even watch them. Weird thing is that I can watch them flawlessly and smoothly with Flash (10.2) and that this only happens when I switch to fullscreen. If you let windowed, even running on 1080p video still plays fine.

I don't remember having this issue before reinstalling so it is possible that some "core driver" is missing? I also made a PRAM and SMC reset...

Help please, I'm really desperate, I just got used at HTML5 and don't wanna go back to Flash.

Thanks!

Edit.

I did what you said and here are my tests results:

Safari with YouTube HTML5 activated could watch flawlessly this video: http://www.youtube.com/watch?v=XITHbsUUlYI at 720p but not with 1080p.
Safari with YouTube5 extension couldn't even watch both 720p and 1080.
Safari with flash 10.2 could watch both smoothly 720p and 1080p

Thing is that I don't understand why in the past I could watch all the videos I wanted at fullscreen regardless if it was either 720p or 1080p using YouTube5. Is it possible that my Mac got some kind of bottleneck or it's blocking its CPU usage?

I get the same lagging with 720p video -- even with flash on youtube. I have a MBA 13" ultimate 4MB RAM 256SSD.

I am not sure if that is related to Safari... or 10.6.7 or what.. But it is annoying. Anyone else?

Post an example video for everyone to test and give you the results. I'm on a C2D MacBook and, from what I remember, 720p videos with YouTube5 play a heck of a lot better than with Flash.

I'm not getting any lag with 1080p youtube videos.

WTF?

We got the same Mac.. Are you using YouTube5 extension? Which version? 2.2.5?

Try this build: https://github.com/downloads/gugod/youtube5/YouTube5-20101209-fix.safariextz

It worked better than the last build, at least I could watch all 720p and 1080p videos but my fans were spinning really fast (almost 4k RPM) and CPU at 74º which is totally retarded.

Here are some tests I made.

Safari with YouTube HTML5 activated could watch flawlessly this video: http://www.youtube.com/watch?v=XITHbsUUlYI at 720p but not with 1080p.
Safari with YouTube5 extension couldn't even watch both 720p and 1080.
Safari with flash 10.2 could watch both smoothly 720p and 1080p

Thing is that I don't understand why in the past I could watch all the videos I wanted at fullscreen regardless if it was either 720p or 1080p using YouTube5. Is it possible that my Mac got some kind of bottleneck or it's blocking its CPU usage?

Shall I try SMC/PRAM reset?

I don't use Youtube5 extension, but if you're talking about just normally watching videos, I can watch 1080p videos without lag perfectly fine.

This is completely ridiculous.

I tried ClickToPlugin HTML5 player and YouTube5 extension again and how's possible that they couldn't even handle 1080p videos while flash can?

Anyone else having this ****ing annoying issue?

I didn't have this before reinstalling Snow Leopard I start to think that I pretty much messed something up...

I can't wait to show my boy that movie:D

I just went back to safari a few days ago from Chrome. I also installed the Safari flash plug in at that time. I had no issues watching the movie at full screen 1080P and my cpu heat stayed under 70C and 2,000 rpm. Running the latest 10.6.7 update.

because certain well known, high profile people lie about Flash..?
